Sermorelin & Growth
Hormone Peptides

Sermorelin is a synthetic growth hormone-releasing hormone (GHRH) — it's not growth hormone itself, but it tells your pituitary gland to release your own growth hormone (GH). This is fundamentally different from injecting synthetic HGH, which bypasses your body's regulatory feedback. Sermorelin restores a more physiologic pattern of GH release, with most of the effect happening during natural sleep cycles. Sermorelin was previously FDA-approved as Geref but is no longer commercially manufactured; it's now available through 503A compounding pharmacies under valid prescription.

HGH (human growth hormone) is direct administration of synthetic GH — high doses, supraphysiologic levels, and bypassing the body's negative feedback regulation. It's effective but has a more significant side-effect profile (water retention, joint pain, insulin resistance, increased risk of certain conditions at high doses). Sermorelin tells your pituitary to release its own GH within physiologic limits — gentler effects, fewer side effects, lower cost, and can't push GH beyond what your body's regulation allows. HGH is FDA-approved for specific conditions (adult GH deficiency); sermorelin is compounded and used for optimization.

Reported benefits include: improved sleep quality and depth (most consistent and earliest-reported effect), increased energy and endurance, faster recovery from exercise, gradual improvements in body composition (modest fat loss, lean muscle support), improved skin elasticity over time, and improved mood and cognitive function in some patients. Effects are typically gradual — most patients notice sleep and energy changes at 2–4 weeks, with body composition changes emerging over 3–6 months.

These are all growth hormone-releasing peptides with slightly different mechanisms: CJC-1295 is a longer-acting GHRH analog that extends sermorelin's effect window; ipamorelin is a ghrelin mimetic that triggers GH release through a different receptor (often combined with CJC-1295 for synergistic effect); tesamorelin is a longer-acting GHRH analog FDA-approved for HIV-related lipodystrophy and used off-label for visceral fat reduction. Janessa selects based on your specific goals, age, lab work, and budget.

At Aera Medical Aesthetics, sermorelin protocols typically run $400–$700 per month including the peptide, injection supplies, and follow-up. CJC-1295 + ipamorelin combinations are typically $500–$800/month. Tesamorelin is more expensive at $700–$1,200/month given its current pricing. Cost varies with current pharmacy pricing — Janessa quotes specific pricing at consultation.

Yes. Before starting any growth hormone-releasing peptide, we run baseline labs including IGF-1 (the downstream marker of GH activity), complete metabolic panel, lipid panel, hemoglobin A1c, and thyroid function. We repeat IGF-1 at 8–12 weeks to monitor response and at 6-month intervals during ongoing therapy. Patients with elevated IGF-1, certain cancers, or severe metabolic disease may not be appropriate candidates.

Sermorelin and ipamorelin are generally well-tolerated. Most-common side effects: injection-site redness or tenderness, mild headache (typically resolves within first week), occasional flushing, transient water retention at higher doses. Rare but possible: insulin sensitivity changes (we monitor with A1c). Patients with active cancer, untreated thyroid disease, or pregnancy should not use these peptides.

Subcutaneous injection (similar to insulin pens), typically administered before bed to align with the body's natural overnight GH release. Most protocols are 5 nights per week with 2 nights off, in 3-month cycles followed by an evaluation. Patients are taught proper at-home injection technique at the start of therapy.

Sleep improvements: typically 1–2 weeks. Energy increases: 2–4 weeks. Recovery improvements: 4–6 weeks. Body composition changes: 3–6 months. Skin elasticity improvements: 6+ months. The earliest and most consistent effect is improved sleep depth — patients often report deeper, more restorative sleep before any other change is visible.
